The plaster is used as a flattening of the interior and exterior surfaces of the buildings and as decorative material. In this study, photon attenuation coefficients of barite plaster containing steel were measured. The measurements performed at 511, 835 and 1275 keV which are obtained from 22Na and 54Mn radioactive sources, using a gamma spectrometer that contains a NaI(Tl) detector and MCA. The measured results were compared with the calculation obtained using computer code of XCOM for 1 keV–1 GeV gamma energies. Also, half value layer (HVL) and tenth value layer (TVL) were calculated using the results obtained from the experimental measurement.

Experimental Values

Mass attenuation coefficients of fly-ash based geopolymers fabricated with different proportions of barite are measured using a high-resolution NaI spectrometer detector. After fabrication, the samples were irradiated with gamma-rays emitted from point sources of 241Am and 137Cs. The measured experimental values are found to be consistent with theoretical calculations carried out using the XCOM program. Based on the results, the radiation shielding capacity of the geopolymers is found to increase with increase in barite proportion. In addition, the fly-ash based geopolymers fall within the internationally established range and are thus acceptable for use as radiation protection devices.
